Historically, geology and mineralogy and comminution, the key pieces of the puzzle that control mineral processing, were only individually considered, but never collectively. Comminution circuits were designed and operated to provide targeted product fineness, or the 80th per centile, and this discrete number was rarely changed. This was reexamined in the late 20th century, however,
